GRATE FOR RANGES,STOVES, OR FURNACES SPECIFICATION forming part of Letters Patent No. 404,595, dated June 4, 1889.

' Application filed February 13, 1389. Serial No. 299,710. (No model.)

Be it known that I, SALVATORE J. BUZZINl,

of'the city, county, and State of New York,

have invented a new and useful Improvement in Grates for Ranges, Stoves, or Furnaces, of which the following is a full, clear, and exact description.

This invention relates to grates and their connections for ranges, stoves, or furnaces of different kinds, in which the grates are made to reciprocate or shake, preferably in straight horizontal directions, for the purpose of freeing the grate and fuel thereon from the accumulation of ashes, and which grates are or may be made to swing from their one side to dump the contents of the fire box or chamber when desired into the ash-pit of the structure. The invention consists in certain novel con structions, arrangements, and combinations of parts in grates of Y the above description and their fire boxes or chambers and connect-- tions, substantially as hereinafter described and pointed out in the claims.- i

Reference is to be had to the accompanying drawings, forming apart of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 represents a front View of a range having my invention applied. Fig. 2 is a vertical longitudinal section upon the line a: min Fig. 3. Fig. 3 is a horizontal section mainly upon the line 3 y in Fig. 2. Fig. 4 is a central vertical transverse section through the range;

and'Fig. 5 is a view in perspective of a means connected with the shaking devices of the I grate, as hereinafter described.

The range, stove, or furnace to which my invention is applicable may be of any suitable construction; but as in the range to which the invention is here shown applied the grate A, that may either be built up in sections or made of a single piece and be either flat or slightly arched, as desired, is arranged to lie and work below the top of the bed-plate B of the fire box or chamber C, in or on which the usual fire-brick linings I) rest. By thus arranging the grate relatively to the bed-plate of the fire-chamber a better freedom of'motion is secured for the grate when shaking it, and to still further attain this end and to prevent jamming of the grate by the fuel on it with the motion of the grate the bed-plate B is provided at its ends with downwardly-bent projections 0, arranged to enter in between the bars d of the grate, so thatwhen the grate is shaken or reciprocated back and forth in direction of the length of its bars said bars cl will work in between the projections c, that in a measure act as teeth to rake the grate, as well as to prevent fuel from passingbe neath the bed-plate. Furthermore, I propose to stud the upper surface of the grate with any number of teeth-like projections e, that when the grate is reciprocated back and forth will also serve to break up the bed of fuel resting upon thegrate.

The grate A, I prefer to reciprocate, for the purpose of shaking itin astraight horizontal direction, and, as here shown, it is thus arranged to operate. ginal side upon a bar D, which is journaled at its ends, as at f f, in the main structure. It is hung upon said baras, for instance, by loose-fitting clips gso as to admit of the sliding of the grate, when being shaken, along said bar and the bar D where it passes through the clipsg, and the clips themselves are constructed to engage with one another-as, for instance, by making such portion of the bar passing beneath the bed-plate to interfere Said grate is hung at its one marand the holes in the clips of square or angular formationso that in rotating or turning the bar D the grate will besimilarly moved in common with it to provide for the dumping of the grate in a swinging direction from its one side by the bar D as a hinge-pin and to provide for the raising of the grate again by means of a handle h on the front end of the bar D, or otherwise.

Upon the opposite marginal side of the grate to that on which the bar D is arranged is another baror rod E, upon the top of which said opposite marginal side of the grate rests, as by toes 2', for the purpose of holding the grate up to its place on its free or dumping side.

This rod E is loosely supported at its inner end within a projection from the main structure, as at 70, and passes freely through a suitably-shaped slot Z at its other end in the front plate of the range, whereby said rod may be laterally swung or adjusted out from under the supporting-toes c of the grate, as shown by dotted lines in Fig. 3. When it is required to dump the grate, as hereinbefore described, and after the grate has been raised again, said rod E maybe returned to its normal position under the toes i to hold the grate up at its free end, and may then be locked in place by a suitably-engaging drop-catch 171.

Both rods 1) and E are fitted loosely to their places in the range, so that they may be drawn out therefrom when required to renew them or to take out the grate through the dooropening in the ash-pit for the purpose of repairing or renewing it. To thus remove the bar D it is first raised at its front end to bring its body in line with the upper enlarged portion of the slot at in the front plate of the range, and through which the whole bar may be drawn and be again inserted to perform its function as a hinge-pin to the grate, a suitably-engaging drop-catch 0 serving to secure it when in place. The invention,however,is not restricted to these or any other precise means for providing for the movement of and securing when in place the bars or rods D E.

The grate A maybe shaken or reciprocated along the rods D E by any suitable means; but, as here shown, this is done very conveniently and perfectly by a lever G, having its fulcrum a on the front of the range and connected below with a slotted arm I) of a slide H, arranged to project within the range and having an aperture 3, with which a hook r on the grate automatically engages when the grate is raised to its place.

I am aware that ash-sifting pans or drawers have been used in stoves, heaters, and furnaces, arranged, as usual, below and independent of the fire-grate and constructed with a grate on their top, beneath which has been a sliding frame provided with teeth that project up between the bars of said ash-sifter grate and serve, as the sliding frame is reciprocated, to rake and separate the ashes from the cinders after both have fallen through the main or fire grate of the structure. Such I do not claim.

I am also aware that the side walls of a fire pot or grate inclosure have been constructed to form stationary grate-bars and that combined with and between them have been a series of in dependent parallel grate-bars, each alternate one of which has been stationary and the intermediate ones reciprocating and extending beyond and beneath the inner walls of their inclosure, and both of such independent grate-bars provided on different parts of their surfaces on which the burning fuel rests with angular shaped lugs, with which either wall of the inclosure 011 the sides parallel to said grate-bars conform. Such,

therefore, also, I do not claim, nor yet in the abstract merely combining stationary rakingteeth with a reciprocating grate; but in the construction which I here show and describe I use a reciprocating grate, each bar of which moves in common with the other and requires to be of no special construction on its face, and construct the bed-plate proper of the fire-chamber, on which the fire-brick lining rests, with downward projections on its opposite sides arranged to enter down between said fire-grate bars to prevent fuel from passing beneath the bed-plate that the upper surfaces of the bars, when the grate is reciprocated, work beneath.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. In reciprocating-grate arrangements for the fire-chambers of ranges and other heating structures, the combination, with the reciprocating fire-grate A, composed of a series of connected parallel grate-bars a, all made to reciprocate in common, of the bed-plate B of the fire-chamber, beneath which the upper surfaces of said bars at their ends work, provided on its opposite sides, which are transverse to the line of motion of the grate, with projections 0, arranged to enter down between the grate-bars, whereby and without specially constructing the grate-surface for the purpose fuel is prevented from being carried by the reciprocating grate beneath the bed-plate to jam or interfere with the free motion of the grate, essent-iallyas shown and described.

2. In a shaking grate for ranges and other heating structures, the combinatiomwith the bed-plate of the fire-chamber, of the reciproeating grate arranged below said bed-plate and provided with one or more clips on its one side and one or more toe rests or supports on its opposite side, a rockin g bar fitted to pass loosely through the clip or clips of the grate and adapted to rock or turn the grate in common with it, and a laterally-movable rod or lever on the opposite side of the grate adapted to pass either under or from beneath the toe rests or supports of the grate, substantially as specified.

3. The combination, in a range or other heating structure, of the reciprocating and laterally dumping grate A, provided with socketlike clips 9 on its one marginal side and toe-rests 'i on its opposite marginal side, the laterally-adjustable rod or lever E on the toe-rest side of the grate, and the rocking bar D, adapted to pass loosely through said clips and to turn the grate in common with it and detachably fitted to its place and through the clips, whereby the grate may be readily removed when required, substantially as specified.
